...and no pics, huh?
hello people well I have designed things for a long time but never really got any thing built do to lack of funds/knowledge of machines that would help I of cores found out what a cnc machine was and have been buying parts to make one from scratch I have had one invention/design stolen I have one other I sell but is hardly any thing I care for (no love for it) well the jift is after finding my design online with the guy I talked to about it back in 2000-2001 I was a little pist and I don't really care to let every thing keep collecting dust on paper
so here is what I have collected so far
3-490oz 2ph stepper motors
3-kl-4030 stepper drives
1-6axis breakout board
1-36v 9.6a p-s
1-1600kw 2hp 24,000rpm liq-cooled spindle
1-1600kw vfd 220v to match spindle
2-lead screws 72"+55"
4-baring mounts(for lead screws)
3-stepper motor mounts
1-v-indexer up to 6" chuck
4-leaner 20mm pillows/bearings
still on list
1-lead screw for z-axis (14-18" travail)
2-72 1-1/4" leaner rods (fully supported)
2-55 20mm leaner rods (semi supported)
2-16mm hollow leaner shafts (for z-axis)
4-20mm shaft mounts
4-1-1/4" shaft mounts
1-home/limit switch?? info please?
1-laptop with windows-xp
1-coolant pump (spindle)
1-coolant reservoir (spindle)
1-coolant radiator (spindle)
1-coolant pump (work)
1-coolant reservoir (work)
4-72" 3-1-1/2" t6 alum 1/4wall
4-55" 3-1-1/2" t6 alum 1/4wall
4-to be determined (still some designing left to z-axis)
the machine is getting started as a 3-axis but is going to end at a 6axis
with the other 3-axis being removable from the work tray
it's length was determined because it will also be used to make molds for body parts (green foam as base form) I figured if I was going to build one I should make it to do every thing rather then make multi-cnc machines
the first 3axis plus spindle is over head and a non moving work tray
will be a concealed cabinet with a funnel screen and filtering set up under the work tray making it really an over sized bench top machine you can use in the house
but I am sure I am missing a lot of need to get components so I am asking if any one has some links for some components parts and suggestions they may have
also if any one has any good places to get some pillow blocks for 1-1/4" that don't cost a $100 or more a piece please let me know or at least a 72"20mm leaner shaft (1-1/4 or larger is all I can find in 72" at a 3time mark up for the pillows bearings etc)
thanks every one in advance
...and no pics, huh?
"Are you gonna eat that?"
its parts collecting at this time no real pics of a started project to show but I can try and get some pics on here soon of the parts if every one would like? or may be try to draw out some rough-draft plans for every one??
go ebay, look for seller "linearmotionbearings" from china...
he got VFD & spindle too... good price.
as for the stepper motor, go for Motion King... simply email their marketing person.
I got 693 Oz.in NEMA34 stepper for US$50. Shipping will offset that a bit, but still cheap.
I do have one good advise for every one though don't buy leadscrews from precision tech machining every one of the screws that I got from them where
bent even the replacements bent!!! sent them back one time they said they where not bent got them back bent as hell
still trying to find some good rails but the length I am trying to get has become a nightmare every thing seems to get ruined during shipping or a company that don't know how to send any thing strait
I sure wish I would have seen this post before I ordered a 48" lead screw kit from Precision Tech Machining. Not only did my lead screw get bent in shipment as mentioned above but the bearing journals were machined too large to fit the bearing blocks that came with the order. Once they got my credit card number it was impossible to get order status information from Wanda, the owner, by phone or email, and the few times she did give me status it turned out to be a lie. Fortunately I only spent $107 with them because it all had to be scrapped.
I originally made this video for Wanda to show here the condition of the package I received but she never bothered to look at it. So I did a little voice over so potential future customers of Precision Tech Machining can judge for their self.
If you are interested in doing business with PrecisionTechMachining.com and you read my previous post regarding an unpleasant experience with bent acme rod and poor tolerances you will be pleased to know that I just received a complete make up order and every thing was perfect.
It turned out that Wanda was away from the company on a family emergency during the time I had trouble. When she returned to work and found out about my issues she immediately contacted me, explained the situation and asked if they could have another crack at sending a make up order.
When I explained that I had scrapped everything from the first she re-shipped the complete order again.
This time the 4' acme rod came completely protected with bubble-wrap and firmly fixed to a 1" X 1" wood slat to protect the rod from bending and damage. The threads were turned perfect with the delrin nut threading with very little friction or backlash. The bearing journals fit snugly into the bearings and motor mounts bolted right up with the provided Love Joy rod coupler. See attached pictures.
Thanks Wanda (the owner), I'm sorry to hear about the emergency that took you out for a while but it is nice to have you back.
